ATTACHMENT FOR WINDOWS ANDTHE LIKE.

Application filed April 10, 1917.

To all `lli/0my 'it may concer/n.'

lle it known that l, JOHN B. CLERMONT, a citizen of the United States, and resident of the borough and county of theBronx, city and State of New York, have invented certain new and useful Improvements in At-.

tachments for lindows and the like, of which the following is a speciiication.

My invention relates to windows in which the sashes are capable of a pivotal movement and to other elements which are hinged or pivoted and has for its object to provide an attachment which may be positioned to automatically cooperate With'a relatively fixed element for the purpose of arresting the pivotal movement of the sash cr the like at predetermined points and which may be brought to an inoperative position when a free and unrestricted pivotal movement of the sash or the like is desired. The particular purpose of my invention is to provide an arrangement in which the intended coperation of the various elements can not be disturbed or interfered with either intentionally or otherwise. My improvement also contemplates constructing the attachment in such a manner that the same can be moved to and from its automatically operative position preferably only by authorized persons, thus protecting the same against tampering and undesired manipulation. Otherl objects of my invention will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings which by way of example illustrate my attachment as applied to a window having sliding sashes capable of swinging on horizontal pivots under certain conditions. In the said drawings, F 'igure 1 is a front elevation of a Window including my attachment with parts in section; Fig. 2 is a section thereof on the line 2-2 of Fig. 1; Fig. 3 is a similar View showing the sash swung on its pivots relatively to the casing; Fig. 4 is an enlarged detail sectional view of one of the reciprocating stays forming part of the attachment; F ig. 5 is a section thereof on the line 5--5 of Fig. 4; Fig. 6 is a detail elevation of the casing showing one of the cam plates adapted to coperate with the stays in face:

nection, forming part of` my improvement, and Fig. 8 is a horizontal section on the line 8 8 of Fig. 6.

My improved attachment as shown in the drawings comprises a steel or other metallic case 10 forming part of orsecured toa plate` 11 provided Awitlran aperture 12. A bridge. pm 13 1s secured to the inside wallofv the case 1() and'projects therefrom into the bore of a tubular sleeve 14-which in turn extends exteriorly of the case 10 through the aperture 12 and is provided with spaced annular flanges 15.. The bridge pin 13 has a sliding fit with the bore of the sleeve 14 whilethe` o uter diameter of the latter is such. as to similarly fit the aperture, 12 so that said sleeve 14 is properly supported by the pin` 13 and aperture 12 and the said pin 13 is itself maintained against transverse displacement by said sleeve. With this construction the sleeve 14 is rotatably mounted the arm 16 by means of a shank 18 as clearlyV shown in Fig. 4. A steel or other metallic split collar 19 surrounds the sleeve 14between the flanges 15 and has its free ends spaced from each other. and connected by means of a pin or the like 2() adapted. to it into the forked or notched end 21 of a cam 2.

22 rotatably mounted in the case 10 on trunnions 23, the common axis Vof thelatter extending transversely to the axis of the sleeve 14. The cam 22 is formed at opposite corners with recesses or notches 24 adapted to receive the nose or projection 25 of a counteraeting spring 26 the free ends of which are set in'opposite corners of the case 10 as illustrated in Fig. 4. As so far described, my attachment is or may be the same as shown and described in my Patent No. 1,150,174 of August 17, 1915. The attachment further includes a cam plate 27 of steel or the like provided with a slot 28 open 30, the latter having a vertical edge 31 l0- cated at the open end of said slot 28 as shown in Fig. 6. The said slot 28 comprises a portion 32 extending at an oblique angle to the vertical path in which the sash travels and inclined downwardly from said open end, said portion 32 communicating with a continuing vertical portion 33 closed at its lower end, as shown in Fig. 6. ,A resilient tongue or clip 34 preferably stamped from the plate 27, extends outwardly from and in registry with the lower portion 33 of said slot-28 as clearly shown in Fig. 6, to form a pocket in the same way as illustrated in my prior patent hereinbefore referred to. At a point adjacent to the projectionl 30 the plate 27 is provided with a stud or the like 35projecting perpendicularly to the surface thereof.

In utilizing the attachment in connection with a window, for instance of the type shown and described in said patent and illustrated herein, the plate 27 is rigidly secured at the proper point to an inside vertical surface of the window casino' 36 by means of screws 37 or the like with the open end of the slot 28 projecting upwardly and toward a vertical groove 38 forming part of said casing. The plate 27 is so positioned on the casing that the projections 29 and 30 extend over said groove 38 whereby the open end of the slot 2S is located in registry with said groove as shown in Fig. 6, and said slot 23 virtually forms a continuation of the groove 38, as will more fully appear hereinafter. The case 10, on the other hand, is set into a recess 39 formed in the adjacent vertical side edge of the sash 40, andthe plate 11 is secured thereto by means of screws or other suitable fastening devices whereby the case, stay-arm and connected parts are fastened to the sash so as to be movable therewith. The sash is further provided with a depression 41 extending upwardly from the recess 39 in said side edge for the accommodation of the stay-arm 16, said recess and depression being so proportioned as to depth, that no part of said stay-arm 16 projects beyond the side edge of said sash in the retracted or inoperative position of these parts of the attachment.V

lVith the described arrangement the cam plate 27 is stationary or fixed relatively to the stayarm 16 and its connected parts.

In windows of the type shown in the drawings, it is preferable, yin order to provide for a maximum pivotal movement of the sash and its complete reversal in the casing, to locate the pivotal connection between the sash cords, chains, or the like 42, and the sash 40, at or near vthe lower corners of the latter. llVith this arrangement.

the sashes are capable of the usual vertical movements and are also adapted to be piv otally moved to reversed positions for cleaning purposes. During such j vertical and pivotal movements of the sashes, the pivotal connection previously referred to travels in vertical directions'and ordinarily would en gage the projections 29 and 30 of the cam plate 27 located as shown and described. In other words` said projections 29 and 30 would arrest the movements of said pivotal connections and thus restrict the vertical movements of the sashes and interfere with the intended pivotal actuation thereof. To overcome this difficulty, I provide an improved connection comprising a tubular pivot member, preferably of substantially rectangular form, to t into the groove 38, said tubular pivot member in its illustrated form comprising legs 43 and 44 connected by a transverse leg 45 and a short leg 46, extending from the leg 44 toward the leg 43 and forming a slot 47 extending lengthwise of the pivot member, as shown in Fig. 8. The leg 43 of said pivotal member 1s preferably connected by means of a pin 48 with a plate 49 which in turn is preferably counter sunk in the edge of the sash 40 and secured in position by means of screws or the like 50, as shown in Figs. 7 and 8.V The legs 45 and 46 are connected by means of a pin 51 to which the end of the sash cord,

chain or the like 42 is connected. By referf ring to Fig. 8 it will be seen that with this arrangement the projections 29 and V30 of the plate 27 are in registry with the slot 47 between the legs 43 and 46 and thus pass through this slot as the sash is moved vertically orpivotally reversed, said sash thus being capable of the maximum intended vertical and pivotal movements without interference or interruption.

Any suitable means may be provided for normally maintaining the sash 40 in its intended vertical path; for instance the construction may include fixed stop beads 52 and movable stop beads 52, the stop beads 52 extending downwardly from the upper portion of the casing 36 and terminating at an intermediate point thereof while the movable beads 52a extendfrom the terminating ends of the beads 52 to the sill of the casing 36. Inv the preferred construction the fixed stop beads 52 terminate at points only slightly above the sash 40 when the latter .is in its lowest position, so that in its pivotal movements, which can only take place when in its lowered position, the upper edge of said sash will pass beneath the fixed beads 52. It will, of course, be apparent that the illustrated and described devices may be replaced by equivalent devices or arrangements. Furthermore, the parts of my attachment are so located and proportioned with respect to each other that in the lowered position of the sash 4() the head 17 of the stay-arm 16 is opposite the plate 27 when the stay-arm is in its inoperative position and is located in the position 32 of 130 the slot 28 when the stay-arm is in its op-` erative position. The purpose of the above arrangements will appear more fully from the description hereinafter.

Vith the parts of my attachment in the position indicated in full lines in Fig. L1 or, in other words, in a retracted or inoperative position, the stay-arm 16, button head 17. and shank 18 are located within the Ydepression 41 and entirely within the confines of the sash 4Q. In this condition, the button-head 17 and its shank 18 will move in a plane or path to one side of or out of registry with the plane in which the plate 27 is fixed on the casing 36 so that the sash 40 may be freely swung on the pivot pins 48 to any extent within the limits of the construction, and reversed when the movable stop beads 52'"L or their equivalents are moved to an inoperative position. as shown in Fig. 3. To secure the desired automatic cooperation betweenthe elements of my attachment carried by the sash 4() and the part thereof located on the casing 36, it is necessary to move the stay-arm 16 in a direction away from the case 10 in order to bring the button-head 17 and its shank 18 into a position where they will automatically coperate with 'the plate 27 and its slot 28 at the proper time to arrest a move ment of the sash 40 on its pivots 48. 1n order that this may be accomplished, any suitable means may be provided; for instance, I may provide the cam 22 with an angular axial opening or recess 53 located in registry with a similar Opening in the case 10 and adapted to receive the angular end of a suitable key or tool, for instance, of the kind shown in my prior patent hereinbefore referred to.

Then it is desired to bring the stay-arm and its connected parts in coperative relation with the plate 27 and its parts, the sash 40 is first raised to a position in which the head 17 lies above the projections 29 and 30 of said plate 27. This upward movement of the sash 40 brings its upper edge above the lower ends of' the fixed beads 52 so that it is impossible to pivotally swing the sash 10 out of the casing 36 at this stage. If the angular end of said key or tool is now inserted into the angular opening or recess 53 and the key or tool rotated in the proper direction the cam 22 will be oscillated on its trunnions' 23. In this man ner the forked or notched end 21 of said cam may be moved toward the right in Fig f1 and owing to its connection with the pin 2() and collar 19 will slide or move the sleeve 111 along the bridge pin 13 also toward the right in said Fig. 4C until the one annular flange 15 engages the plate 11 and arrests the sliding movement'of said sleeve 14, the nose or projection 25 of the spring 26 being' forced ont of the one notch 24 of the cam 22 and finally snapping into the other notch-24; to secure said cam and its connected parts in the adjusted position. In its movement along the bridge pin 13 as described, the sleeve 141 carries with it the stay-arm 16 and thus moves the latter away from the window sash 4f() and into the groove 38 of the window casing 36 above the projections 29 and 30 of the plate 27, so that the arm 16 and its connected parts now occupy the position indicated approximately by dotted lines in ivig 4 in which the shank 18 of the button-head 17 is in the same plane with the slot 28 of' the plate 27; in other words the projections 29 and 30 of said plate 27, with this adjustment of the stay-arm 1'6, are in the vertical path of said shank.

If the sash 10 is now moved downwardly to its lowest position in the casing 36, the shank 18 will engage and ride along the surface 31 of the projection 30 and will finally engage the projection 29 and he cammed thereby into the portion 32 of the slot 28. Thus while the sash el() still occupies its normal position at the lower portion of the casing 36 and before it has ,been pivotally actuated, the shank 18 already occupies a position in the slot 28. In

this lowest position the upper edge of the sash 4:0 is below the ends of the fixed heads 52 as shown in Fig. 2 and is free to be pivotally moved as soon as the nioval'iie stop beads 5.1 are opened as shown in Fig. 3. 1f the sash 40 is now swung on its pivots 4:8 out of the casing, said shank 18 will travel lengthwise of the portion 32 of the slot 28 and into the portion 33 thereof while the button-head 17 will be carried along and will finally move below the tongue or clip 341 and press the same against its tension, said head 17 finally reaching the pocket formed thereby so that said. head 17 will be firmly held and enga-ged by said clip and accidental movement of the head and shank in a reverse direction out of the slot will be prevented. As the said shank 18 and head 17 thus move along` the slot and become seated therein the free end of the stay-arm 16 will be held and said arm will describe a pivotal movement on the pin 13 relatively to the case 10 and sash et() as the latter is pivotally swung and will thus arrest said pivotal movement of said sash and firmly hold it in an inclined position relatively to the window casing 36 as shown in Fig. 3. ln this position of the parts a space exists between the two sashes of the window through which air enters and passes out thus securing perfect ventilation without any direct drafts. rllhe attachment also permits the lower edge of the sash to be raised slightly to produce a space between said lower edge and the window sill whereby double ventilation may be At the same time the the accidental conn pivotal movement 4 oi the sash in case the locking strips 52 should be accidentally lett in their open or inoperative positions. To return the sash to its normal. upright position in the casing it is only necessary to bring,` the lower end of the sash to its lowormost position and then exert a suiiicient pressure on said sash toward said casing to o.f'ercome the tension exerted by the rlip 234 on the head 17. This will cause the shank 18 to move in a reverse direction in said slot but not completely out o'j the portion 32 thereof, and will iinally bring vthe sash bai1V to its upright position in the casing` 86 as shown in Fig. 2, hitter the stop beads 52 have been again closed the sash may be 'freely moved in vertical directions without danger of any pivotal movement. As the sash is raised the shank 16 passes out oi" the portion 62 of the slot2S, the head 1T being located in the groove 38 and vertically movable therein with the sash. lach time the latter is brought to its lowest position the shank 18 passes into the portion 32 oit said slot 2S, so that the parts ot my attachment are automatically brought into cooperative engagement before the sash 4() is in a position in which it can be pivotally moved, that is if the stay-arm 16 occupies an operative position as shown by dotted lines in Fig. 4. In its inoperative position the stay-arm and connected parts simply pass by the plate 27 and its correlated elements without engaging` therewith.

It an attempt is made to disarrange the cooperation oi: the parts for instance by raising the sash 36 in the direction indica ted by the arrow a in Fig. 3 in an attempt-to withdraw the shank 18 from the slot 2S, the outer end of the arm 16 will move upwardly in the arc of a circle with said shank as a center as indicated by the arrow 7; in said Fig'. 3, and will finally abut against the stud 35 on the plate 27 whereupon further movement of the arm aud of the sash in the indicated directions is arrested. It isy thus impossible to bring about a disarrangement of the cooperation between the parts in this manner. Similarly by having; the projections 29 and 30 of the plate 27 extend over the groove 38 and into the verticalV path of the shank 18, it is absolutely impossible for said shank 18, it the' parts are in their operative position, to pass the projection 29, so that the shank 18 is forced to enter the slot 28 each time the sash is vertically moved; that is to say the parts are so positioned on the window casing and window sash respectively that a coperative engagement of one with the other is assured each time thc sash is brought down to its lowest point and providing the stay-l arm 16 is in its outward position so that an automatic action is absolutely guaranteed. Y

If the sash 40 in itsnormal vertical position is moved upwardly in the casing 36 to disengage the shank 18 from the portion 32 of the slot 26, and an attempt is made to pivotally swing,` the sash out of said casing` for the purpose ot destroying the operative correlation between the stay-arm 16 and plate 27, it will be found that this is impossible. This is due to the Jfact that theparts are so arranged and proportioned with respect to eachother that an upward movement ot' the sash 40 of suicient extent to remove thc shank 16 out of the slot 28 or the portion 62 thereof brings the upper edge of said sash npwardly beyond the lower ends of the xed beads 52. The latter thus prevents a pivotal movement of the sash 40 so that it is Y impossible to disarrangethe mechanism in this way; at the same time, as long` 'as the stay-arm is in operative position, it is im: possible to pivotally swing the sash out ot the casing until said stay-arm 16 and plate 27 are in operative connection with each other. Similarly it an attempt is ma( e to swing,` the stay-arm 164 downwardly about the bridge pin 13 as a center and with the sash in a raised position, the projection 29 of the plate 2i' will be engagedy by the shank 1S and prevent such displacement ot the arm. T he device, therefore, is absolutely tool proof in all respects and a proper coperation between the parts is assured whenever this is desired. When a complete or tree pivotal movement of the sash 40 is desired, thc sash 40 in its upright position is raised in. the casing a distance suflicient to bring` the shank 18 and head 17 above the plate 27V, after which the end of the aforementioned key or tool is simply inserted into the aperture 53 and properly actuated to operate the cam 22 in a direction to slide the sleeve 14 toward the left in Fig. 4 until the one flange 15 engages the wall of the casing 10. This operation forces the nose 25 of the spring; 26 out of the right hand notch 24 and causes it to finally snap into the left hand notch 24 of the cam 22 when the iinal retracted position of the parts has been reached. The actuation of the sleeve 14 as just described will also move the stay-arm 16`in the sante direction and return it into the depression 41 in which condition the arm as well as the head 17 lie entirely within the conlines of the sash and out of the plane in which the projections 29 and 30 and slot 28 are located. H- the locking strips 52 or their equivalents are now moved to an open or inoperative.Y

position the sash 40 may be brought to its lowest positionand freely swung to any post tion within its limits of oscillation and may thus for instance be readily and easily reversed for cleaning or other purposes withllO out making it necessary for the cleaner or other person to step outside of the window. By having the parts normally in their outer position so that the projection 29 of the plate 27 is normally always in the path of the shank 1S and head 17 the danger of accidental complete pivotal movement of the sash out of the casing and resulting injuries either to the sash or to persons within range are absolutely prevented and the complete pivotal movement of the sash is possible only after the parts have been adjusted as de scribed with the aid or" said key. The counteracting spring 26 is so arranged that an attempt to move the arm 16 to an inoperative position by exerting a pressure toward the sash therein will be completely counter'- acted. The attachment is thus positive in its operations and completely safeguarded against tampering by unauthorized persons, it being 'understood that other more complicated devices may be substituted for the key and key hole construction shown in the illus tration to still further guard against such contingencies.

In describing the attachment I have referred to the same in the singular although in practice I prefer to provide duplicate parts at the two opposite vertical sides of the window, it being evident however, that in some cases a single attachment located at one side thereof will be sufficient to secure the intended results. In addition to this it will be readily apparent that the attachment is not limited to use in connection with windows and that the same may readily be combined with other movable elements when a limitation of movement in a certain direction is desired as, for instance, in doors and the like.

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention.

I claim:

1. The combination of a relatively stationary frame, a window sash or the like vertically and pivotally movable therein, a case carried by said window sash or the like, a bridge pin in said case, a sleeve slidably and rotatably mounted on said bridge pin, a stay arm secured to said sleeve to move therewith, a projection on said arm, a slotted plate secured to said frame, an abutment forming a continuation of said plate and extending into the vertical path of said proj ection whereby the latter is stopped by said. abutment and directed thereby into said slot to swing said arm on said bridge pin and arrest the pivotal movement of the sash or the like, member rotatably mounted in said case and connected with said sleeve, means for actuating said member to slidably move said sleeve on said bridge pin whereby said arm and projection are moved to and from an operative position and means for locking said member in its adjusted positions.

2. The combination of a window casing having a vertical groove, a window sash vertically and pivotally movable in said casing, a stay arm pivotally connected with said sash, a projection on said arm movable vertically in said groove and a slotted plate secured to said casing, an abutment forming a continuation of said plate and projecting over said groove into the vertical path of said projection whereby the latter is stopped by said abutment and directed thereby into said slot to arrest the pivotal movement of said sash.

3. The combination of a window casing having a vertical groove, a window sash vertically and pivotally movable in said casing, a stay armpivotally connected with said sash, a projection on said arm movable vertically in said groove, a slotted plate secured to said casing and projecting over said groove into the vertical path of said projection whereby the latter is arranged to automatically enter said slot and arrest the pivotal movement of said sash and a stud projecting perpendicularly from said plate arranged to engage said arm and arrest its movement as said sash. is moved vertically in an attempt to disarrange the coperation between the slot and projection.

In testimony whereoil I have hereunto set my hand.
